Patent number: 10073749Abstract: A combination of a component-based automation framework, software-based redundancy patterns, and a distributed, reliable runtime manager, is able to detect host failures and to trigger a reconfiguration of the system at runtime. This combined solution maintains system operation in case a fault occurs and, in addition, automatically restores fault tolerance by using backup contingency plans, and without the need for operator intervention or immediate hardware replacement. A fault-tolerant fault tolerance mechanism is thus provided, which restores the original level of fault tolerance after a failure has occurred—automatically and immediately, i.e., without having to wait for a repair or replacement of the faulty entity. In short, the invention delivers increased availability or uptime of a system at reduced costs and complexity for an operator or engineer by adapting automatically to a new environment.Type: GrantFiled: December 4, 2015Date of Patent: September 11, 2018Assignee: ABB Schweiz AGInventors: Ettore Ferranti, Manuel Oriol, Michael Wahler, Thijmen de Gooijer, Thomas Gamer
